I have got a broken screen on my xperia u,the phone still turns on but you cannot see a thing.My contacts are all on the phone memory is there any way of getting them.Thanks
Are your contacts from your Google account, or are they only on the phone? If they're from your Google account, they should be synced to the cloud, and you should be able to see them in Google Contacts on the web.
If they're only on the phone, then you could try plugging the phone in to your computer using a USB cable. Then use the appropriate Sony software that should allow you to sync or backup your contacts--find it here: Computer software - Sony Smartphones (US)
